Briefly describe: The sulfur vulcanization process containing organic accelerators is divided into four stages? Answer: 1? The interactions between the various components of the vulcanization system result in the formation of intermediate compounds; these intermediate compounds act as vulcanizing agents. 2? These intermediate compounds interact with the rubber, resulting in the formation of reactive side groups on the rubber molecular chains. 3? These reactive side groups interact with each other or with the rubber molecules, thereby forming cross-links. 4? Further reactions of these cross-links.
Answer: (1) The interactions between the various components of the vulcanization system yield intermediate compounds, which function as vulcanizing agents in practice； (2) The interaction between intermediate chemicals and rubber generates active side groups on the rubber molecular chains ； (3) These reactive side groups interact with each other or with rubber molecules to form cross-linking bonds ； (4) Further reaction of the cross-linking bonds.

Briefly describe: The sulfur vulcanization process containing organic accelerators is divided into four stages? Under certain conditions, a chemical reaction takes place between the raw rubber in the compound and the vulcanizing agent, causing the linearly structured macromolecules to crosslink and form three-dimensional network structures, thereby endowing the compound with excellent properties such as high strength, high elasticity, good wear resistance, and corrosion resistance
